EXPERIMENTAL INVESTIGATION AND HEAT TRANSFER ANALYSIS OF INNOVATIVE THERMAL MECHANICAL REFRIGERATION SYSTEM COMPARED TO ELECTRIC COMPRESSOR
( American Society of Mechanical Engineers (ASME) , 2022 , Conference)The current electric refrigeration and air condition systems are major causes for ozone depletion and global warming. These systems consume large percent of the worldwide gross production of electricity (around 17%). ... -
Recycling low grade waste heat to electricity
( Canadian Institute of Mining, Metallurgy and Petroleum , 2013 , Conference)Most mining and metallurgical industries produce relatively large quantities of low grade waste heat which they vent, for the most part, to the environment. To date, little is being done to recover some of this heat and ... -
Geothermal energy extraction from decommissioned petroleum wells
( International Society for Rock Mechanics , 2014 , Conference)Abandoned wells impose enduring liabilities to petroleum companies and/or governments. However, the depth and abundance of abandoned petroleum wells make them an economically attractive source of geothermal energy. Geothermal ... -
